Full-automatic production equipment for expanded perlite core board of fire door and production method thereof

Abstract

The invention relates to full-automatic production equipment for an expanded perlite core board of a fire door and a production method of the full-automatic production equipment, relating to the technical field of fire-proof thermal insulation materials. For the full-automatic production equipment, a front lapping device, a rear lapping device, a rolling pressing device, an automatic switching-off device, a microwave drying device and an automatic demoulding device are assembled on a stander of the full-automatic production equipment, wherein a material supply device is mounted above the front lapping device; the material supply device comprises a mixing blender; a material outlet hopper is assembled on the mixing blender; the material outlet hopper is provided with a front material outlet and a rear material outlet. When in work, the full-automatic production equipment completes the production through the front lapping device, the material supply device, the rear lapping device, the rolling pressing device, the automatic switching-off device, the microwave drying device and the automatic demoulding device. The production method comprises the steps of: preparing materials, stirring materials, feeding materials, lapping and paving materials, rolling pressing, switching off, curing, sizing, dewatering, cutting edge, demoulding and stacking. The full-automatic production equipment and the production method of the full-automatic production equipment have the advantage of excellent and stable product quality, and are suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of fire-proof and heat-insulating materials, in particular to a fully automatic production equipment and a production method for expanded perlite fire-proof door core boards. Background technique [0002] As an inorganic mineral product with excellent performance, expanded perlite has the characteristics of high temperature resistance, non-combustibility (class A1 fireproof material), and environmental protection. The above characteristics make expanded perlite have excellent thermal insulation, heat insulation, sound insulation and other properties. Products (especially plates) can be widely used in the fields of fire door inner core, building exterior wall insulation, high-rise building lightweight partition walls, fireproof and heat insulation decoration materials, sound-absorbing decoration materials (such as highway, high-speed railway sound baffles), etc. And it has very huge application prospect and m...

Problems solved by technology

[0003] The production of expanded perlite sheet products has always been in the state of small-scale manual operations, especially the production of large-scale sheets, and there are very few manufacturers in the country; due to the backward production technology and the low degree of mechanization, the production of expanded perlite sheet products The efficiency and production capacity are extremely low, which is far from meeting the current market demand. The main reasons are: the molding process of expanded perlite products is difficult, the production cycle is long, the labor is large, the production site is large, and the transportation cost is high.

At present, domestic production enterprises basically use vertical pressing to produce expanded perlite slabs, that is, use cold presses or hot presses to produce expanded perlite slabs through batching, molding, pressing, drying and other production processes. It can press one piece or several pieces, which is heavy work and labor-intensive; in addition, the finished slabs must be dried or dried naturally, and the drying time generally reaches 20 to 72 hours, and it takes several days or even more to dry naturally. In a few weeks, continuous production cannot be realized at all, which seriously affects the production scale and supply capacity of the production enterprise; at the same time, the quality of the finished product is difficult to control, and the density, flatness, mechanical strength (especially moisture content), thermal conductivity The quality indicators cannot be controlled, and even the weight of each piece of product is different, and the local density and thermal conductivity of the same piece of product are uneven, which seriously affects the use and construction quality of downstream enterprises.
